Ulifac v6 with CPC464 and VR40007

Hi

I have recently repaired a CPC464 board where several chips had been fried. The board is now passing diagnostic tests and loads fine from tape however I purchased a Ulifac to go with it but am having issues.

The VR40007 is one that Charlie confirms should work with the Ulifac v5b but he has not tested with the v6.

I have cleaned and cleaned the connectors and even given them a lite sanding but usually get a constantly rebooting screen, corruption or a black screen.

Sometimes I will get a normal ready prompt and have managed to load diagnostics 1.3 from tape. It detects and tests the 512kb upper ram ok but fails on the rom test.

None of the ulifac command seem to work or once in a while will lock up the machine.

So has anyone else tested the v6 Ulifac with a VR40007 gate array? or know if any of the changes to the ulifac between 5b and 6 would cause issues?

Thanks
